BOTTLE-BLOWING MACHINE.

Specification of Letters Patent.

Patented Feb. 17, 1914;

Original application filed April 3, 1912, Serial No. 688,213. Divided and this application filed September 5 13,1912. Serial No. 720,114. j

To all whom it may concern:

Be it known thatI, THOMAS C. DUFFIELD,

a citizen of the United States, residing at Bridgeto'n,-in the county of Cumberlandand State of New Jersey, have invented certain new and useful Improvements in Bottle- Blowing Machines, of which the following is a specification.

My invention relates to improvements in bottle blowing machines, and more "particularly to improved mechanism for cutting 011 the molten glass as it is supplied to the molds.

A further object is to provide improvements of this kind in which the cutting op eration is controlled by the downward pressure of the glass holding rod, so that by a single movement of the rod, the glass may be supplied to the mold and cut oil.

This is a division of my application for patent filed April 3, 1912, and givenSerial No. 688,213. I

With these and other objects in view. the invention consists in certain novel features of construction and combinations and. arrangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings: Figure 1 is a sectional plan view illustrating the location of my improved cutter in connection with my improved bottleblowing machine. Fig. 2 is a view in longitudinal section through the cutter, and Fig. 3 is a bottom sectional plan view on the line 33 of Fig. 2. I

2 represents a. supporting post around which a table 9 is mounted to turn and is given a step by step feed by means of sultable mechanism forming the subject matter of my pending applications, and-hence need not be described here in detail, except to say that the molds 13 which are positioned radially on the table, are moved in turn to a position below my improved molten glass cutter which will now be described in detail.

The first operation is that of placing the nioltenglass in the mold, and this operation is performed by a workman who takes the glass from the molten mass in the ordinary way upon a rod, and this-rod he holds above a ring 100 which extends through an opening 101 in a horizontal bar 102. This bar 102 is secured at one end to an upright post 103 and the latter at its lower end is fixed to a bracket 104 secured to base 1. On the is fulcrumed between its ends on a pin 109in a bracket 110 de-' I.

pending from bar 102.

An arm 111 fixed to lever 108 is pivota'lly connected to the cutter 105,

to a sleeve 112 adapted to slide on post 103. The sliding movement of this sleeve 112 is limited by collars 113 fixed to the post by set screws 114. The free end of lever'108 is connected to a plunger 115 which extends upwardly through a slot 116 in cutter 105., and through an opening 117 in the bar 102. A cross bar 118 is fixed to the upper end of plunger 115, pressed by'pressing on the cross bar 118, the cutter will be operated to cut off the molten glass. 111 other words, the operator guides the glass through the ring 100, and when the proper amount is in the mold, he depresses plunger 115 with his rod, so that he cuts 011' just the amount of-glass desired.

The cutter 105 is held in proper cutting positionby means of a cross bar 119 through which bolts 120 project. These bolts extend through openings in bar 102, and have nuts 121 on their upper ends between which and the bar 102, coiled springs 122 are located and exert upward pressure on the cutter.

One end of lever 108 is forked and pivotally connected .75 and when this plunger is de-'- the glass holding rod hold it firmly against the under face of,- 0

bar 102.

Various slight changes might be made in the general form and arrangement of parts described without departing from my invention, and hencgl do not limit myself to the precise details set forth. but consider myself at liberty to make such changes and alterations as fairly fall. within the spirit and scope of the appended claims. I

" Having thus described my invention, what 4 I claim as new and desire to secure by Letters Patent 1s:

1. The combination with a supporting bar having a glass guldlng ring and an opening 111 rear of the ring, of'a cutter mounted to slide rgainst the lower face of said bar andmovable across said ring, said cutter having a'longitudinal slot therein, a pivoted lever connected. to said cutter, and a plunger passing through said opening in the bar "and through the slot .inthe blade and connected to the lever, so that the depression of the plunger causes the pivoting of the lever and the sliding movement of the cutter, substantially as described.

2. *Tlie'conibination with a supporting bar bracket'on tliebar, a lever fulcrumed between its ends on said bracket, an upwardly opening 1n the projecting arm on said. lever connected to the cutter, a plunger passlng through the "and connected to one end of said lever, and

means at the other end of said lever limiting l the pivotal movement thereof, substantially as described. I r i 3. In combination with a glass guiding ring adapted to barj supporting said ring; a cutter mounted to slide below the bar, a plunger movable by a rod holding the molten glass, a dependbar and the slot in the cutter,

l goeaase ing bracket onthe bar, a lever fulcrunied on the bracket and to which said plunger is p be supported above a mold i in position to direct glass into the mold, a

pressed by a glass connected, and an arm on said lever connected to the cutter and adapted to more the cutter across the lower endofthe ring when said lever is actuated substantiallyas described. w

4. In combination with a molten glass cutter comprising a bar a glass guiding ring in said bar, a knife mounted to slide below the barya depending bracket on the bar, a lever tulcrumed on the bracket an arm on said lever connected to the knife and adapted to more the knife across the lower end of the ring when said lever is moved, a plunger connected to said lever and projecting through the bar and adapted to be deholding rod to inove the lever, a post, a sliding sleeve on the post to which one end of said lever *is pivotally connected, and collars. fixed to the postlimiting the movement of the sleeve, substantially as described."

in testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
